During this last step, the mold and brick therein slide off the forward end of the cover directly upon the pallet, where the brick are ejected from the mold by any well known means, not shown.

It will of course be understood that the relative horizontal planes of the mold tracks 9 and the pallet supporting tracks 1 and 11 are such that the bottom of the mold and the top of the pallet will be maintained in substantially the same horizontal plane with the cover or liner plate therebetween'.

After the mold has been stripped from the brick at C position the mold is returned to A iosition by any approved means, not shown, and the cycle of operation just described is then repeated indefinitely.

Having thus described my invention:

What I claim as my invention is:

1. A brick making machine. having a mold supporting means and a pallet supporting means adapted to receive and slidably support the mold and pallet thereon, said mold supporting means and said pallet sup porting means also adapted to maintain the bottom of the mold and the top of the pallet in the same substantially horizontal plane, a fixed thin smooth liner sheet adapted to rest beneath the mold and upon the pallet, and means for transferring the mold across the face of the liner sheet directly to said pallet without disturbing the substantially horizontal position of the mold.

2. A brick making machine having a mold supporting means and a pallet supporting means, a thin smooth apertured liner plate positioned between the horizontal planes of said surfaces in contact with the bottom of the surfaces, and means for sliding a mold after the mold has been filled with mud on top of the pallet, said liner plate having openings therein adapted to permit the passage therethrough of excess brick making material and the marginal forward edges created by said openings being bevelled.

6. A brick making machine comprising a fixed thin smooth liner plate, means for slidably supporting a mold and a pallet in contact respectively with the upper and lower surfaces of said liner plate, and means on said mold for engaging the pallet whereby when said mold is pushed across and beyond the end of said plate and out of contact therewith said pallet will move correspondingly and the mold will be deposited on the pallet.

7. In a brick making machine, a thin smooth liner plate for slidably supporting the brick in a brick mold, said plate having apertures therein for permitting escape therethrough of surplus brick making material.

8. In a brick making machine a smooth thin apertured liner plate, a mold above and a pallet below said plate, means for advancing the mold and pallet in registered relation across the aperture in said plate, means for clamping the mold, liner plate and pallet together, before filling the mold, and means for simultaneously sliding the mold and the pallet out of contact with the liner plate and into contact with each other.

In testimony whereof I afiix my signature.

A brick making machine having a mold supporting means and a pallet supporting means, a thin smooth liner plate and means for supporting the same between the bottom of a mold and the top of a pallet, means for clamping the mold and the liner plate and the pallet together, and means for simultaneously sliding the mold and the pallet out of contact with the liner plate and into contact with each other.

4. A brick making machine having a mold supporting means and a pallet supportin means, a thin smooth liner plate between said surfaces, and means for sliding a mold after the mold has been filled with mud on top of the pallet, said liner plate having openings therein adapted to permit the passage therethrough of excess brick making material.
